[On Christianity:] Its lip-service and its empty rites have made it the easiest of all tasks for the usurer to cloak his cruelties, the miser to hide his avarice, the lawyer to condone his lies, the sinner of all social sins to purchase the social immunity from them by outward deference to churches.

A great love is an absolute isolation and an absolute absorption.

Christianity is a formula: it is nothing more.

Scandals are like dandelion seeds--they are arrow-headed, and stick where they fall, and bring forth and multiply fourfold.

Charity is a flower not naturally of earthly growth, and it needs manuring with a promise of profit.

Love, the one supreme, unceasing source of human felicity, the one sole joy which lifts the whole mortal existence into the empyrean, was by it [Christianity] degraded into the mere mechanical action of reproduction.

Christianity has ever been the enemy of human love; it has forever cursed and expelled and crucified the one passion which sweetens and smiles on human life, which makes the desert blossom as the rose, and which glorifies the common things and common ways of earth. It made of this, the angel of life, a shape of sin and darkness ... Even in the unions which it reluctantly permitted, it degraded and dwarfed the passion which it could not entirely exclude, and permitted it coarsely to exist for the mere necessity of procreation.
